“Nature uses only the longest threads to weave her patterns, so that each small piece of her fabric reveals the organization of the entire tapestry.”
That is how Professor Richard Feynman concluded the first lecture, The Law of Gravitation, which was part of a seven lecture course titled ‘The Character of Physical Law’ which he delivered at Cornell in 1964.
It is an interesting and engaging lecture about the nature of gravity, gravitational fields, the attraction of masses and how people like Newton, Galileo, Copernicus and others discovered how the planets were organised and also how Newton was able to join the pieces of the puzzle and come up with the famous:
F = GMm/r2
Feynman was a brilliant physicist, he won the Albert Einstein Award , the E. O. Lawrence Award, the Nobel Prize in Physics (1965) the Oersted Medal in 1972, National Medal of Science and others. Yet his greatest gift was his ability to explain complex ideas in simple language.
Aptly called “The Great Explainer” Mr Feynman was a brilliant teacher. This is made evident in a physics textbook based on his lectures The Feynman Lectures on Physics. The lectures were given to undergraduate students at the California Institute of Technology (Caltech), during 1961–1963.
In three volumes Feynman explains diverse topics, from mechanics to electromagnetism and quantum mechanics. The book has been called the most popular physics textbook ever written and it is easy to see why. Feynman had a way of simplifying things for his audience.
The good news is that Feynman’s lectures are now freely accessible on the web, some videos and the full text of the book.
If you are a physics buff or someone interested in refreshing your physics knowledge or just looking to understand how some physical phenomena works, this book is the best you can get. And for no charge.
You won’t be disappointed.
